The laity carry out their manifold apostolate both in the Church and in the world.  We wish to list here the more important fields of action, namely, church communities, the family, youth, the social milieu, and national and international levels. Since in our times women have an ever more active share in the whole life of society, it is very important that they participate more widely also in the various fields of the Church's apostolate.

50 years after the above words were written, Cardinal Kasper said:

Jesus, please help Pope Francis promote co-responsibility of the laity
